South Carolina Code of Laws § 12-6-3587 states that “A credit may not be allowed for a solar system unless the system is certified for performance by the nonprofit Solar Rating and Certification Corporation or a comparable entity endorsed by the State Energy Office.” Instructions for certification of solar hot water heaters and PV systems are below; for all other equipment, taxpayer should retain with tax records a copy of the manufacturer’s certification that the equipment meets federal tax credit eligibility requirements of 26 USC § 25D.

I. The Solar Rating and Certification Corporation certifies solar hot water systems. Taxpayers seeking the Solar Energy System Credit for a solar hot water system should keep a copy of their certification and receipts for equipment and installation with their tax records for documentation in case of an audit.
